What is the best way to call a script from another script?


The usual way to do this is something like the following.

test1.py

def some_func():    print 'in test 1, unproductive'if __name__ == '__main__':    # test1.py executed as script    # do something    some_func()

service.py

import test1def service_func():    print 'service func'if __name__ == '__main__':    # service.py executed as script    # do something    service_func()    test1.some_func()


This is possible in Python 2 using

execfile("test2.py")

See the documentation for the handling of namespaces, if important in your case.

In Python 3, this is possible using (thanks to @fantastory)

exec(open("test2.py").read())

However, you should consider using a different approach; your idea (from what I can see) doesn't look very clean.


Another way:

File test1.py:

print "test1.py"

File service.py:

import subprocesssubprocess.call("test1.py", shell=True)

The advantage to this method is that you don't have to edit an existing Python script to put all its code into a subroutine.
